FORT WAYNE, Ind. (www.incnow.tv) -- In this week's episode of Cool Science Monday, Martin Fisher from Science Central will talk about ultraviolet light.

It’s a very short wavelength of light, which is not visible to the human eye. There are numerous forms of UV light, ranging from very short wavelengths to extremely short wavelengths.

Unlike incandescent light, which comes from something hot – a hot light bulb, glowing lava, a fire – ultraviolet is considered cool light. UV light is capable of making some things fluoresce. They absorb the invisible UV light and release brightly colored visible light.

Martin used a black light and showed some items that fluoresce, such as anti-counterfeit strips in money, paint on a picture, a safety vest.
